We have three buckets filled with leftover solder paste from our screen printing process. Kester has informed me that they no longer take paste, but only dross and pot dumpings. Does anyone know if there's someplace I can recycle this, or am I goin

Check out ECS refining, they will recycle your paste and dross and cut you a check. We usually send 1 55 gal drum of dross and 1 55 gallon of waste and get a check back for ~$150. You can also contact the solder suppliers they usually have recycle

Note that not all pastes are equal. You need to test the paste you use to see how long it continues to print well. I have used paste that prints the same after 24 hours on the stencil and some that barely makes it to 8.

I wouldn't mix it in a jar with new paste. But in another jar to be used on the next job, sure. I mean if your concern is contaminates, doesn't that mean its contaminated on the stencil? Unless the board is a hard one to print, or has really tiny

We use an evaporation system to eliminate the need to dispose of any wastewater, you may want to look into this, big cost savings in the end. We recycle the wasted paste with our dross.

Corroding the cleaning fluid? OK I still don't under stand? Does your screen printer recycle the fluid and the paste is mixing with it?
